what is kinefelter syndrome?
Klinefelter syndrome is a chromosomal condition that only affects males and is characterized by a male having an additional X chromosome (XXY) in cells. This chromosome ab…normality occurs when there is an error in cell division, resulting in an extra copy of the X chromosome.
It is estimated that about in in 500 men have Klinefelter's syndrome.
Most of the Klinefelter Syndrome affected persons can lead a life which could be considered as normal. However, they might have certain problems related to sexual organs,… (among others), and some, - but not all -, could be infertile. The reason for this is their extra chromosome. Females have XX chromosomes, Males have XY chromosomes, and Klinefelter syndrome affected males have XXY chromosomes. They often are prescribed testosterone therapy.

Mutation of a gene is not necessary for Klinefelter's Syndrome. Itis an autosomal disorder meaning that an entire chromosome failedto disjunction during anaphase and so there …are 2 X chromosomes anda Y chromosome.
Klinefelter's, is a mutation, so a person with such disease, would have normal parents (XY, XX). Klinefelter's is the result of nondisjunction of the sex chromosomes, causing …trisomy of the sex chromosome, (XXY) not because of a mutation in the somatic cells of the parents, but instead of the mutation in the gametes (sex cells) of the parent.
The genotype for Klinefelter's is XXY, so the outward appearance is a male with some feminine features like breast development, less facial hair, small testes, and infertility….

About 1/1000 to 1/500 males have Klinefelter's syndrome.
Physically, no; mentally, that's up to the strength of the individual.
they have a extra chromosome, a normal male is XY, a male with klinefelters is XXY.
Klinefelters syndrome occurs in a male and it is when they carry and extra X chromosome having a total of 47chromosomes rather than the usual 46. Thus resulting in a chromosom…al mutation.
once every 500 to 1000 males
